The codes came back today, po134 and po154. Checked the live data and it showed around .450v for both sensors. These O2 senors were new and came with the setup, not sure of the brand name. All the wire harness and setup is for a 2002 1500 Silverado with the 5.3/4l60e 2wd.
UPDATE: This is what I've done so far. Checked my grounds, good, checked the O2 sensor wires and connections, good, I did find the exhaust down pipes had lost a nut on both sides and were loose on both sides. I'm using 10-15 Camaro exhaust and cat delete down pipes. I put four new bolts and fasteners on and have ordered new O2 sensors. When I drive it to the car show tomorrow, I'll be a watch out for any codes.
